Dentigerous cysts are developmental odontogenic jaw cysts, commonlymanifesting in the 2nd and 3rd decades of life. This article presents an extremely rare case of dentigerous cyst showing increased uptake in the peripheral rim on bone scan. Herein, we discuss the clinical, radiographic, and histologic features of dentigerous cysts as well as the pathological mechanism underlying their activities on the bone scan. Bone scan was a sensitive tool for detecting the biologic activity of dentigerous cyst in our case.
